To all whom it may concern:

Be, it known that I, GUSTAV G. FORESTER, a citizen of the United States, and resident of Bagley, in the county ofGuthrie and State oflowa, have invented an Improvement in Gasolene Engine and Pump Drains, of which the following is a specification.

My invention is an improvement in gasolene engine and pump drains, and consists in certain novel constructions and combinations of parts hereinafter described and claimed.

Referring to the drawings forming a part hereof, Figure 1 is a side elevation of my improvement partly in section. Fig. 2 is a section on the line 22 of Fig. 1. Fig. 3 is a detail of the draining valve and the mechanism connected therewith; and Fig. 4 is a section on the line 44 of Fig. 2.

In the present embodiment of my invention, the cylinder a of the pump A is connected by a pipe a with the cooling tank B, and by a pipe a with the engine cylinder (3, and a valve casing c is interposed in the length of the pipe a a check valve 0 being arranged within the casing. The lower part of the cylinder is formed into a cylindrical chamber a one of the ends a of the chame ber, being enlarged to form a circular valve seat a upon which is seated a drainage valve a the valve being secured to one end of a shaft a journaled in the chamber (L The valve a is disk-like in form, and is provided with an aperture a therethrough, adapted to register with a slot (0 in the valve seat, when the valve a is in certain positions. The opposite end of the shaft a is squared as at a" and secured thereon is an arm at having pivotally connected to one end thereof a link a. The link 0, is slidable longitudinally of the cylinder 0, being mounted in bearings a on one of a pair of brackets a arising from the cylinder, and having journaled in the free end thereof a shaft a. One end of the shaft (L15 is provided with a pulley a and the other end is provided with a governor D, comprising a collar d fixed to the end of the shaft and provided with oppositely projecting lugs d to which are pivotally connected weighted levers d. A sleeve d is slidably mounted upon the shaft and the said sleeve is also provided with oppositely projecting lugs (Z and levers d are pivotally connected with lugs d and with the weighted levers d near the outer ends thereof. A spring d is arranged between the collars, and the collar d is provided with a disk d for engaging the upper end a of the link a, when the governor is in certain positions, the said upper end of the link being arranged at an angle to the main portion and cam-shaped as shown in Fig. 2. A spring a is' arranged between a collar a secured to the link, and one of the bearings a" before described, for normally maintaining the link in its uppermost position. A pinion (L is secured to the shaft a and meshes with a gear wheel a journaled on a stud shaft a connected with one of the brackets a, and the gear wheel (L21 is provided with a wrist pin a connected by a link a with the piston of the pump.

It will be evident from the description, that when the pump is in motion, the rotation of the shaft will tend to move the weighted levers d outwardly, owing to centrifugal force. l/Vhen the centrifugal force attains a certain point, the movement of the weighted levers will move the sleeve d to bring the disk into contact with the angular portion of the link, whereby to move said link downward, and to rotate the disk valve a. This valve is so arranged that the aper ture a in the valve will 'register with the slot a in the seat when the pump is at rest, that is, when the link a is in its uppermost position. The shaft a before mentioned, is provided within the chamber a with an arm a, and tothe free end of the arm are pivotally connected links a, a, one of the links a other, a, projecting towards the engine cylinder. The links a, (1 are slidable throu h bearings in spiders a, secured within t e pipes (1., a, and are adapted to engage with their free ends the check valve 0 before men tioned, and a check valve 1) within the cooling tank. The valves 1), c are supported by arms 5, c pivoted to the free end of the pipe at, and to the inner face of the casing a, respectively. l/Vhen the pump is at rest, and tie drainage valve open, the check valve 0 will also be open, and the valve 1) will be closed, since the links a, (1, will both be moved in the direction of the engine cylinder.

l/Vhen the pump is in operation, and the link a, is depressed, whereby to rotate the projecting towards the cooling tank, and the shaft a and close the disk valve, the check valve 0 will be closed, and the valve 6 will be opened, thus permitting the passage of fluid from the cooling tank to the pump, and from thence to the engine cylinder, from which a pipe a discharges into the cooling tank. When the pumpis stopped, the drainage valve and the check valve in the pipe leading to the engine cylinder will be opened, and the valve in the pipe leading to the coo1 ing tank will be closed, thus permittlng a free drainage of the engine cylinder and the P Wliere the shaft 00 passes through the end wall of the circular chamber 05, a stuffing box 0, is arranged, and the valve casing c is provided with a screw cap 0 whereby access may be obtained to the casing. A check valve (1 is provided at the opening of the pipe a into the cylinder a to prevent back flow of the fluid from'the cylinder to the cooling tank on the downward motion of the piston. The valve (I132 is secured to an arm a which is pivoted as at a to the pipe, and the valve is slotted as at (L to permit the passa e of the link a.

claim:

1. The combination with the engine cylinder and the cooling tank, of a pump comprisin a cylinder, the bottom of said cylinder being formed into a horizontal cylindrical chamber, one end of the chamber having its exterior formed into a valve seat, said seat being provided with a slot leading into the cylinder, a shaft journaled in the cylindrical chamber and provided on one of its ends with a disk valve resting on the valve seat, an arm on the other end of the shaft, brackets con nected with the opposite end of the cylinder, a shaft journaled in the brackets, and provided on one of its ends with a governor, one of said brackets being provided withbearings, a link connected with the arm of the shaft and slidable through the bearings, the upper end of said link having an inclined portion, a governor on the end of the shaft, a sleeveslidable on the shaft and moved by the governor, said sleeve having a disk for engaging the inclined portion of thelink, a piston in the pump, means whereby said shaft may drive the iston, a pipe leading from the cylinder to t e cooling tank, a pipe leading from the cylinder to the engine cylinder, a check valve in each of said pipes, one of said checks opening toward the cooling tank, and the other towards the engine cylinder, said shaft in the cylindrical chamber beingprovided with an arm, links connected with the arm and adapted for engaging the check valves when the shaft is rotated, and a check valve between the cooling tank and the cylinder, said check valve opening towards the cylinder, said disk valve being provided with a perforation adapted to register with the slot of the valve seat when the pump is in an inoperative position' 2.
